Overview: The Rolls RS81B is a professional full-featured AM/FM digital tuner in a single rack-space, designed for commercial and educational applications. It features both automatic and manual tuning and can store up to 30 favorite station presets.

Tuner: The RS81B features a PLL (Phase Lock Loop) Quartz Synthesizer AM/FM Tuner with RDS. Stations can be tuned in either Automatically or Manually and can be stored in one of 30 station memory presets.

  • RDS: The tuner is RDS (Radio Data System) compatible and can display additional broadcast information such as the name of the station and the name of the program. Both an AM loop antenna and an FM wire antenna are included with the tuner.
  • PTY (Program Type Search): This feature lets you to search for broadcast types like News, Weather, Sports, Music genres, and more.

Controls on both include; number buttons for accessing the 30 station presets, Tuning +/- buttons, a Memory button for storing stations, Band, a Stereo/Mono button, and a Display button for accessing any RDS information. Stations can be "scan-searched" or their frequency directly entered using Direct mode. A front-panel signal strength meter will indicate the general strength of an incoming FM or AM signal.

Outputs: The RS81B includes a stereo pair of balanced XLR jacks and a pair of unbalanced RCA jacks for outputting the signal to an amplifier, mixing board, or receiver.

Headphone: A front-panel 3.5mm (1/8") headphone output is provided, along with a Headphone Level control.
